Laravel 4: 502 Bad Gateway with Nginx only in one view - php

Question

I have a strange error in my server with nginx because I was working on this project for many months and everything is working fine except just for one view/page I added because is showing me 502 Bad Gateway but I don't why.
I already deleted the whole html of that view just to print a simple text but is the same
I already removed the whole functionality from the controller just to render the view but is the same
I already changed the route and the name of the controller but is the same
I have tried many things but the problem still persisting and in the log of my server block is showing only this:
Nginx server block error log
2015/08/05 08:25:42 [error] 2423#0: *885 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 187.189.190.62, server: stage.mywebsite.com, request: "GET /business/user/site.com/edit HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "stage.mywebsite.com", referrer: "http://stage.mywebsite.com/business"
php-fpm error log

And that's all
Now I'm going to show you my nginx configurations for the block and the nginx.conf
Nginx.conf

}
Nginx server block

}
location / {

rewrite ^/(.+)/$ /$1 permanent;
try_files $uri $uri/ /index.php?query_string;
}
}
I'm using Nginx 1.8 on CentOS 7.
I hope you can help me.
